Suppose that a medical test has a 92% chance of detecting a disease if the person has it (i. e., 92% sensi- tivity) and a 94% chance of correctly indicating that the disease is absent if the person really does not have the disease (i. e., 94% specificity). Suppose 10% of the popu- lation has the disease. (a) What is the probability that a randomly chosen per- son will test positive

Atechnician compares repair costs for two types of microwave ovens (type i and type ii). he believes that the repair cost for type i ovens is greater than the repair cost for type ii ovens. a sample of 6767 type i ovens has a mean repair cost of $79.79$â˘79.79. the population standard deviation for the repair of type i ovens is known to be $19.18$â˘19.18. a sample of 5555 type ii ovens has a mean repair cost of $75.24$â˘75.24. the population standard deviation for the repair of type ii ovens is known to be $21.40$â˘21.40. conduct a hypothesis test of the technician's claim at the 0.050.05 level of significance. let Îź1Îź1 be the true mean repair cost for type i ovens and Îź2Îź2 be the true mean repair cost for type ii ovens. step 2 of 4 : compute the value of the test statistic. round your answer to two decimal places.
